BT-105
Thank you for your purchase of the AirTurn BT-105 Wireless
Page Turner. We hope you enjoy the wonderful convenience of
hands-free page turning, effects (FX) management and other
creative ways to trigger events with the BT-105. Please send
your suggestions and comments to [e-mail].
Description
The BT-105 will work with most
Bluetooth-equipped MAC and PC
computers. No additional software
is required. It also works with most
momentary switches to activate
the Page Down and Page Up
functions of most document and
presentation programs, such as Adobe Acrobat, Microsoft
Word, and PowerPoint. The BT-105 can be used with one
footswitch to turn pages forwards only, or with two footswitches
to turn forwards and backwards.
The BT-105 also works with select apps for Apple iOS™
iPhones, iPads, and iPods, in addition to Bluetooth-equipped
Android devices with apps that have been designed to be
compatible with the BT-105.
The BT-105 consists of a power switch, two 3.5mm stereo
jacks for footswitches, an LED indicator, and a mini-USB
charging port for the internal rechargeable battery.

5
Setup and Pairing
To use the BT-105 with your MAC, PC, or iPad, make sure the
host computer you are using is in discovery mode. (Check the
instructions that came with your computer or Bluetooth USB
dongle. For iPad users, go into “Settings”, then select
“Bluetooth” and make sure it is turned on). Turn on the BT-105
by pressing the red power button and holding for 1 second.
The LED will blink 3 times and attempt to pair with your
computer. Your host computer may require validation to accept
pairing from the BT-105. If it requires a code, use 0000. If you
are presented a code to validate the BT-105, accept it.
On the iPad, under the “Devices” heading within the Bluetooth
settings, you should see the BT-105 appear, either as a
keyboard, or as “AirTurn” with a serial number. Touch on top of
Serial Number to connect and complete the pairing process.
Once connected, it will blink green once every 2 seconds.
Resetting the Pairing
To reset the pairing on the BT-105, turn it on, wait 3 seconds,
press and hold the red button for 8 seconds until the LED
blinks a rapid series of green and red, then release. If pairing is
unsuccessful, delete the device displayed on the host
computer and reset the BT-105 pairing again. Initial discovery
may take up to 30 seconds (longer on some older PC and
MAC computers). To delete the BT-105 from the iPad’s
Bluetooth Device listing, tap the blue arrow button next to BT-
105’s serial number and connection status text (“Connected” or
“Not Connected”), then press the “Forget this Device” button.

6
Note: You must reset pairing for both devices every time you
change to a different host device such as using it with your
desktop computer and then with your iPad.
Turning off the BT-105
Turn off the BT-105 by pressing
the red button for 2-3 seconds
until the LED turns red. Release
and the LED will blink 3 more
times while the unit shuts down.
Turning power off on the host
computer will automatically turn
off the BT-105 after 3 minutes.
Modes
There are four modes that come ready to use on your BT-105.
Modes are used to send different signals to the host computer,
depending on the computer and the application being used.
The default mode, (Mode 3), is set for page turning on tablet
computers such as iPads and Androids. The other most
commonly used mode, (Mode 1), is for the generic use of page
turning on the PC or MAC.
To change to the PC or MAC mode, (Mode1), turn off the BT-
105. Then, holding down the footswitch plugged into Port 1-2
(the jack closest to the red switch), turn on the BT-105.
Release both the footswitch and power switch as soon as you
see the LED blink. The LED will then blink red, then green,
then red, indicating the mode has been set.
Power Ports 1&2 LED Ports 3&4 USB

7
To change the mode back to the iPad mode, repeat the same
procedure using the footswitch in Port 3-4 (the jack closest to
the USB port). Keep the switch depressed until you see the
first blink, then release the footswitch and power switch. You
will then see one red blink, then 3 green blinks, then one final
red blink. The following table shows each mode and respective
signals:
Mode 1 set using switch 1 on startup (PC/MAC Mode)
Port 1 PgUp Port 3 PgDn
Port 2 Left Arrow Port 4 Right Arrow
Mode 2 set using switch 1 and 3 held together
Port 1 1 Port 3 3
Port 2 2 Port 4 4
Mode 3 set using switch 3 held on startup (Default Setting
– “iPad Mode”)
Port 1 Up Arrow Port 3 Dn Arrow

iOS Virtual Keyboard
Some applications require the use of the keyboard to enter text
or to interact with the application. Since the BT-105 is an
external keyboard, the iPad or other iOS device by default
disables its own virtual keyboard.
To activate the virtual keyboard, open any text box on the iPad.
Then quickly press the power switch while the BT-105 is
connected to the iPad. If you close the virtual keyboard from
within the application, you can repress the power switch to
activate it again. This is a toggle switch so pressing it will
toggle the virtual keyboard on and off. Note that iPhones may
require toggling on the keyboard for each use.
Charging
Please charge your BT-105 1-2 hours using the min-USB to
USB charging cable and any USB wall power adapter, or 6
hours connected to your computer. Note some portable
computers may not sufficiently charge the BT-105. Disabling
the sleep setting on the computer may improve charging
performance.
Your BT-105 should last 100 hours or many days on a charge
depending on how much you use it. On a full charge, the LED
will blink green. When the power is low, the LED will blink as
follows:
Yellow every second = under 25% power
Red every second = under 10% power

9
If the BT-105 is turned off while charging, the LED indicator will
not light up, but it will still charge. If you leave the BT-105 on
while it is charging, the LED will remain lit and you can monitor
the charging status. Red is a low charge, solid yellow is a 75%
charge and orange/green is a full charge.
Note: If you fail to charge your battery when it begins blinking
red, you risk running it down completely which may require a
replacement battery. Charge the BT-105 at least once per
month to maintain good battery health.
Compatible Switches
Most normally open (NO)
momentary switches will work well
with the BT-105. Please visit:
http://airturn.com/faq-pedals/faq-
compatible-pedals for a list of
compatible switches. Some
footswitches have a latch mode. Be
sure that the latch mode is turned off and/or the momentary
mode is turned on. Port 3-4 is used to turn to the next page,
and Port 1-2 is used to turn to the previous page.
For best results use the AirTurn ATFS-2 footswitch or the Boss
FS-5U footswitch with AirTurn patch cables. Check the AirTurn
store or your dealer for cable adapters for other brands of
footswitches.
Two adapter cables are provided to work with most ¼” phone
jack-equipped switches.

10
Tongue and Bite Switches
Tongue and Bite Switches are also
available from AirTurn or your dealer for
special uses. They are
used the same way as
any other momentary
switch.
See the specific instructions included with
each switch.
Troubleshooting
The BT-105 is not connecting or pairing
1. Turn off the BT-105.
2. Delete the AirTurn device on your host computer. On an iOS
device, go to the Bluetooth settings, (Settings, General,
Bluetooth), and press the arrow next to the AirTurn selection
and then press the Forget this Device button, then OK.
3. Turn off Bluetooth on the host device.
4. Turn on the BT-105. Wait 3 seconds. Then hold the power
button for 8 seconds until you see the LED light blink red/green
rapidly several times.
5. Turn on Bluetooth on the host device.
6. The BT-105 should appear after 5-10 seconds depending on
the host.

11
7. Touch or click the listing when it appears and it will connect
after another few seconds.
The BT-105 is connecting but not turning pages
1. Check the mode. This is the most common problem. (It can
be inadvertently changed while turning on the BT-105 by
holding down the footswitch plugged into port 1.)
To change the mode to the default mode 3:
A. Turn off the BT-105.
B. With one hand, hold down the right footswitch, (the one
plugged in closest to the USB port.)
C. Turn on the BT-105.
D. Release the footswitch and power switch after 1 second
or after you see the first green blinking light.
E. When you see a red blink, three greens and a red blink
the mode is changed.
2. Make sure you are using an app that supports the BT-105.
(Check the AirTurn website. http://airturn.com/apps/apps)
3. Check the application instructions to make sure you have
the application set up for the AirTurn.
4. On an iOS device, be sure you are not running too many
applications. Press the Home button twice to see what
applications are running. They will be showing in a row at the
bottom of the screen. If there are many, close them and try
again. To close the apps, touch and hold one until they all start
to wiggle. Press the minus key to close them.

12
5. Lastly, on an iOS device, try resetting the network. (Note:
this procedure will cause you to lose network password
settings and they will have to be re-entered.) Select General,
Settings, Reset, Reset Networks. Recheck connection after the
device restarts.
Go to www.airturn.com/support for more information and
videos on the BT-105. Additional questions can be emailed to
support @airturn.com.
Unit Identification
The unit name in your Bluetooth host consists of several codes
to help with support and identifying your specific device. For
example:
AirTurn105v128-220A
105 refers to the model number.
V128 refers to the firmware version.
220A refers to the MAC address.
This is helpful if there are many BT-105 units in the same
location. Your MAC address will always be the same so you
can easily identify your unit. You will find your specific MAC
address labeled on the bottom of your BT-105.

13
DIGIT
The AirTurn BT-105 DIGIT is a combination Bluetooth
transceiver that may be used in a variety of
settings. It offers a keypad with six
switches. The switches are also used to
change the unit’s mode and send different
characters in each mode. The DIGIT may
also be used with up to four momentary
footswitches, tongue or bite switches and in
a whole array of environments. (Please see
BT-105 instructions for pairing, charging
and other important information.)
Setting Modes on the DIGIT
1. Turn the DIGIT off.
2. Hold down the key symbol(s) for the mode you would like
to select.
3. Turn on the DIGIT.
4. Release the key as soon as you see the first LED light
flash.
You will see the LED blink red once, green for X number of
times based on the mode number, and then red one more
time. For example, when the Down Arrow is selected for mode
3, the red light will blink once, green 3 times and red once.
Your DIGIT comes programmed ready for mode 3. The
following chart shows all the options for each mode:

Two ATFS-2 Pedal Board Kit
The BT-105 or DIGIT may be
purchased with 2 ATFS-2 silent
footswitches. This option is ideal
for many applications in which
two switches are needed. For
example, it could be used to go
forward or backwards in a page-
turning application.
The ATFS-2 footswitch uses a
combination of rare earth metals to
close the switch, making it silent
and highly reliable for a very long
time. There are no mechanical parts to break.
Mode Management
Please see the section in the BT-105 for mode management.
The right footswitch is plugged into port 3 and the left switch is
plugged into port 1.
Important: Be careful not to hold down one of the switches
while turning on the unit, as it may inadvertently change the
mode.
If you are using the DIGIT with the Pedal Board kit, see the
DIGIT section for mode management.

16
Four ATFS-2 Pedal Board Kit
The four ATFS-2 Pedal Board Kit
comes equipped with either the
BT-105 or the DIGIT. Each
footswitch is plugged into the
ports in order from left to right.
You may change modes using
the footswitches as per the Mode
directions in the BT-105 section, or using the DIGIT buttons as
described in the DIGIT section of this manual.
The BT-105 or DIGIT is held in place with hook and loop
fasteners so that it may be easily removed and used as a
standalone controller or with other footswitch systems.
There are many apps that work with the four-pedal board, such
as Jamup, OnSong, PrompterPal, and many more. Check out
the app section of the website for more options.

17
BOSS FS-5U Footswitches
The BT-105 or DIGIT may be used
with one or two BOSS FS-5U
footswitches. Special cables from
your dealer or AirTurn are required
and are supplied when it is
purchased as a kit. For extra
convenience in using the FS-5U,
you can slide the two switches
together.
It is also important to check the
“polarity” switch on the FS-5U.
Please make sure it is pushed to
the right when operating with the
BT-105 or DIGIT.
The FS-5U switches are plugged into ports 1-2 and 3-4 of the
BT-105/DIGIT. See the manual sections for the BT-105/DIGIT
for more information for use.

18
BOSS FS-6 Footswitches
The BT-105 or DIGIT may also be
used with the BOSS FS-6
footswitch. Note that the FS-6
requires a separate 9V battery to
function. AirTurn supplies specially
made cables to function with the
FS-6. You can also make your own
cables with instructions available
on the AirTurn website.
You may choose to have either one FS-6 or 2 FS-6 devices
attached to your BT-105 or DIGIT. There is a different cable for
each configuration. The cable plugs into the center jack of the
FS-6. Be sure to set the switches on your FS-6 as shown here:
Please note the position of each switch. The A pedal has the
Mode and Polarity switches pointing away from each other and
the B pedal has both switches pointing towards each other.
You can slide the FS-6 switches together to make a 4-pedal
configuration by aligning the channels on each one and then

19
sliding one inside the other’s channel. Due to impedance
issues on the FS-6, you may need a splitter cable to change
modes.
Changing Modes
The BT-105 comes set up by default to Mode 3 which will work
with most applications. To change the mode, you will need to
use the splitter cable provided with your unit (Dual FS-6 units
only). To change to Mode 1, insert the splitter into port 1/2,
(closest to the red power switch), on the BT-105. Then plug the
cable coming from the FS-6 into the white end of the splitter to
change to Mode 1, or the black end of the splitter for Mode 2.
For Modes 3 and 4, plug the splitter into port 3/4 of the BT-105
and use the white cable for Mode 3 and the black cable for
Mode 4.
Turn off the BT-105.
Hold down the A pedal. Turn on
the BT-105. As soon as you see
the BT-105 start to blink green,
release the A pedal and the
power switch. You will first see a red light blink, then a number
of green lights blinking that correspond to the mode number,
and then one green light blink. If you do not get that result, try
again. The timing is about 1 second before you must release
the power button and footswitch .
See the BT-105 section for details on characters associated
with each mode.

20
Custom Implementation
There are many environmental options that the BT-105 can be
placed in, including external power, use with custom codes,
embedding with special switching, use with Behringer pedal
board and more. Please see the support section of our website
for details. (http://airturn.com/bt-105/support/bt-105)
